Python爬取Google图片（2021.11.21编写）

傻瓜版代码，先修改储存目录和webdriver路径，再输入网址和图片数量就能用了。

from selenium import webdriver
import time
from lxml import etree
import random
from urllib import request
import os

def pic_url_get(num):
    for i in range(num):
        time.sleep(random.uniform(0,2))
        content = driver.page_source
        html = etree.HTML(content)
        pic_url = html.xpath('/*;q=0.8,application/signed-exchange;v=b3;q=0.9')]
        request.install_opener(opener)
        name = os.path.split(pic_url)[-1]
        if '.' not in name:
            name = name + '.jpg'
        try:
            request.urlretrieve(pic_url, r'C:UsersmsiDesktopgoogle{0}'.format(name))
            print(name + '下载完成！！！')
        except:
            request.urlretrieve(pic_url, r'C:UsersmsiDesktopgoogle{0}.jpg'.format(a))
            print(str(a) + '下载完成！！！')
            a+=1
if __name__ =='__main__':
    if os.path.isdir(r'C:UsersmsiDesktopGoogle'): #修改成你想要存储到的地方
        pass
    else:
        os.mkdir(r'C:UsersmsiDesktopGoogle') #修改成你想要存储到的地方
    num = int(input('请输入你想要下载的图片数量(整数)：'))
    pic_urls = []
    url = input('请输入你想要下载的谷歌图片网址：')
    driver_path = r'G:Pythonchromedriver' #修改成你的chromedriver的路径
    driver = webdriver.Chrome(executable_path=driver_path)
    driver.get(url)
    first_pic_button = driver.find_element_by_xpath('//div[@id="islrg"]/div[1]/div[1]/a[1]')
    first_pic_button.click()
    pic_url_get(num)
    print(pic_urls)
    pics_download()
    print('-----------------------------------爬取完成------------------------------------------')
